According to one example, a tibial bearing component for articulation with a medial condyle and a lateral condyle of a femoral component in a knee replacement procedure is disclosed. The tibial bearing component can include a distal surface and an articular surface opposing the distal surface. The articular surface can include a medial compartment and a lateral compartment configured for articulation with the medial condyle and the lateral condyle of the femoral component, respectively. The lateral compartment can have a lateral articular track with a lateral anterior-posterior extent. The lateral articular track can comprise a plurality of distal-most points along a proximal surface of the lateral compartment that are contacted by the lateral condyle during rollback of the femoral component. The medial compartment can differ in configuration from the lateral compartment and can have an anterior lip height of between about 9 mm and about 13 mm.

Prosthesis system including tibial bearing component

An orthopedic knee prosthesis is provided including a tibial baseplate component having a distal, bone-contacting surface with one or more fixation structures extending distally therefrom, in which the fixation structures are asymmetrically arranged within the baseplate periphery.

Tibial baseplate with asymmetric placement of fixation structures

An orthopedic tibial prosthesis includes a tibial baseplate with features designed for use with small-stature knee-replacement patients. The tibial prosthesis may include a shortened tibial keel, tibial keel fins which define a large angle with respect to a longitudinal axis of the keel, and/or tibial keel fins which extend along less than the entire longitudinal extent of the keel.

Asymmetric tibial components for a knee prosthesis

An orthopaedic tibial prosthesis includes a tibial baseplate with features designed for use with small-stature knee-replacement patients. The tibial prosthesis may include a shortened tibial keel, tibial keel fins which define a large angle with respect to a longitudinal axis of the keel, and/or tibial keel fins which extend along less than the entire longitudinal extent of the keel.
